Case #2: Greater than 4 GB of Physical Memory
Greater than 4 GB of Physical Memory
In this case, the amount of memory remapped is the range between TOLUD and 4 GB.
This physical memory is mapped to the logical address range defined between the
REMAPBASE and the REMAPLIMIT registers.
Example: 5 GB of Physical Memory, with 1 GB allocated to Memory Mapped IO:
•
•
•
•
•
Populated Physical Memory = 5 GB
Address Space allocated to memory mapped IO = 1 GB
Remapped Physical Memory = 1G B
